I am trying to decide the best Level 2 charging station. It will be partially sheltered outside, so I am looking at hard wired versions. I know the Clarity has a 6 kWh on-board charger, so believe I need 7.2 kWh. And am looking at 30/32 Amps, which I believe means I need 40 Amps from the junction box. Am trying to gather all the information my installer needs as well as pick out a reliable brand. I don't think I need the timers or wifi options and would rather keep it simple. Any advice would be greatly appreciated.
